Blockade of Africa in the context of "West African"

West Africa, also known as Western Africa, is the westernmost region of Africa. The United Nations defines Western Africa as the 16 countries of Benin, Burkina Faso, Cape Verde, The Gambia, Ghana, Guinea, Guinea-Bissau, Ivory Coast, Liberia, Mali, Mauritania, Niger, Nigeria, Senegal, Sierra Leone, and Togo, as well as Saint Helena, Ascension and Tristan da Cunha (a United Kingdom Overseas Territory). As of 2021, the population of West Africa is estimated at 419 million, and approximately 382 million in 2017, of which 189.7 million were female and 192.3 million male. The region is one of the fastest growing in Africa, both demographically and economically.

Historically, West Africa was home to several powerful states and empires that controlled regional trade routes, including the Mali and Gao Empires. Positioned at a crossroads of trade between North Africa and sub-Saharan Africa, the region supplied goods such as gold, ivory, and advanced iron-working. During European exploration, local economies were incorporated into the Atlantic slave trade, which expanded existing systems of slavery. Even after the end of the slave trade in the early 19th century, colonial powers — especially France and Britain — continued to exploit the region through colonial relationships. For example, they continued exporting extractive goods like cocoa, coffee, tropical timber, and mineral resources. Since gaining independence, several West African nations, such as the Ivory Coast, Ghana, Nigeria and Senegal — have taken active roles in regional and global economies.

The Atlantic slave trade to Brazil occurred during the period of history in which there was a forced migration of Africans to Brazil for the purpose of slavery. It lasted from the mid-sixteenth century until the mid-nineteenth century. During the trade, more than three million Africans were transported across the Atlantic and sold into slavery. It was divided into four phases: The cycle of Guinea (16th century); the cycle of Angola (17th century) which trafficked people from Bakongo, Mbundu, Benguela, and Ovambo; cycle of Costa da Mina, now renamed Cycle of Benin and Dahomey (18th century - 1815), which trafficked people from Yoruba, Ewe, Minas, Hausa, Nupe, and Borno; and the illegal trafficking period, which was suppressed by the United Kingdom (1815–1851). During this period, to escape the supervision of British ships enforcing an anti-slavery blockade, Brazilian slave traders began to seek alternative routes to the routes of the West African coast, turning to Mozambique.

The liberated Africans of Sierra Leone, also known as recaptives, were Africans who had been illegally enslaved onboard slave ships and rescued by anti-slavery patrols from the West Africa Squadron of the Royal Navy. After the British Parliament passed the Slave Trade Act 1807, which abolished Britain's involvement in the slave trade, the Admiralty established the West Africa Squadron to suppress the trade in cooperation with other Western powers. All illegally enslaved Africans liberated by the Royal Navy were taken to Freetown, where Admiralty courts legally confirmed their free status. Afterwards, they were consigned to a variety of unfree labor apprenticeships at the hands of the Nova Scotian Settlers and Jamaican Maroons in Sierra Leone. During the 19th century, it has been estimated by historians that roughly 80,000 illegally enslaved Africans were liberated by the Royal Navy.
